Precision Laboratory Transfer Coating Machine for Lithium Ion Battery Electrodes

Product Overview

This precision laboratory transfer coating machine is engineered for accurate electrode-sheet production in lithium-ion battery research and pilot-scale manufacturing. The integrated line unwinds foil, applies prepared slurry evenly to the substrate, dries the wet coating, pulls the web through the process, and rewinds the finished electrode. This coordinated workflow helps keep coating dimensions and coating weight within the required process window before downstream cell fabrication.

The equipment supports cathode and anode electrode preparation using aluminum foil and copper foil substrates. It is suited to continuous and intermittent coating processes for lithium iron phosphate, ternary cathode materials, graphite anodes, and related battery slurry systems. Battery R&D centers, pilot lines, materials laboratories, and process-development teams can use the system to prepare coated electrodes for subsequent calendering, slitting, cell assembly, and electrochemical evaluation.

Built around dedicated unwinding, coating-head, oven, traction, rewinding, and electrical-control sections, this unit provides a practical production sequence for demanding electrode work. Its specified web-handling capacity, electric-heated drying section, controlled operating environment requirements, and defined slurry acceptance conditions provide a clear foundation for repeatable operation when process materials and facility services are properly maintained.

Key Features

• Integrated Electrode Processing Line: The equipment combines unwinding, coating, drying, traction, rewinding, and electrical control in one coordinated system. This arrangement supports a continuous material path from prepared slurry application through finished roll collection.

• Continuous and Intermittent Coating Capability: Both cathode and anode processing support continuous and intermittent coating modes. Teams can select the coating pattern required by their electrode design and downstream cell-format workflow.

• Up to 300 mm Coating Width: The unit supports a maximum coating width of 300 mm for both electrode types, with a 400 mm roller-face width. This provides working capacity for laboratory and pilot electrode formats while retaining a defined web-handling envelope.

• Defined Cathode and Anode Process Windows: The system is specified for cathode slurry based on lithium iron phosphate, ternary materials, and similar systems using NMP, as well as graphite anode slurry using DI-water. Distinct solid-content, density, viscosity, coating-weight, and speed ranges give process engineers a concrete starting point for material qualification.

• Electric-Heated Six-Meter Oven: A single-layer oven with three 2 m sections provides 6 m of drying length. Electric heating and a maximum oven temperature of 140 degrees C support thermal processing after slurry deposition before the coated web reaches the winding stage.

• Robust Roll Handling Capacity: Both unwinding and rewinding sections accept rolls up to phi 200 mm diameter and 100 kg. The roll interface accommodates 3-inch, approximately 76.2 mm internal-diameter cores up to 450 mm long in metal, ABS plastic, or paper construction.

• Process-Matched Operating Speeds: Mechanical no-load speed reaches a maximum of 3 m/min. Specified coating speeds are 0.5 to 2 m/min for cathodes and 0.5 to 3 m/min for anodes, allowing the line to be aligned with material system, wet-process characteristics, coating thickness, solids content, and drying temperature.

• Clear Facility Integration Requirements: Defined electrical, compressed-air, exhaust, fresh-air, environmental, and floor-loading requirements help procurement and engineering teams assess installation readiness before commissioning. These requirements support stable utility supply and appropriate operating conditions for coating work.
